its not strange. Books represent knowledge and ideas. Ways of thinking. An attempt to ban a book is an attempt to restrict freedom of thought and the exchange of ideas. It has a historical context and a ban is generally considered on a societal level, not building specific. Some books are not allowed in school buildings, they are not banned.

Banning books for example has a very different context than banning cocaine. Cocaine use in the United States is banned, Hustler magazine is not. I can swing by the store tomorrow and pick one up legally, I can't get cocaine legally.

Restricting Hustler from a school full of kids is not banning it. Thus the quirk.

If I don't allow Green Eggs and Ham in my house does it belong in a museam of banned books?

>a ban is generally considered on a societal level

no, its not.

>Restricting Hustler from a school full of kids is not banning it.

only if you are making up your own definition of "ban".

by any dictionary definition, it is completely appropriate to say hustler is banned from the school.
